The thermodynamic properties of material are one of the important factors for its practical applications, so it is necessary to conduct in-depth research on the parent compound Pb10(PO4)6O. In this paper, we employed the first-principles method combined with the quasi-harmonic Debye model approximation calculations to study Pb10(PO4)6O. Key thermodynamic quantities of Pb10(PO4)6O are presented. For example, at 300 K, the bulk modulus value is 155.4 GPa, the coefficient of thermal expansion is 3.04 × 10–5 K–1, the entropy is 24.05 J/mol K, the vibration free energy is 1.12 KJ/mol and the specific heat capacity at constant volume is 22.25 J/mol K for the system at 10 GPa. Comparing with the results at 900 K, it is found that bulk modulus, bulk expansion coefficient and fixed volume heat capacity are more weakly affected by temperature, while the entropy and vibration free energy are strongly affected by temperature.

AZO nanostructures were synthesized via a sol–gel method followed by supercritical ethanol drying, with Eu incorporated at 0.5 and 1% concentrations. Various analytical techniques were used to investigate their properties. X-ray diffraction (XRD) confirmed a hexagonal wurtzite structure in both AZO and Eu:AZO nanostructures. While Eu-doping slightly reduced crystal quality, crystallite size remained largely unchanged. Lattice parameters increased due to Zn2+ substitution by Eu3+. Diffuse reflectance spectroscopy (DRS) revealed an enhancement in reflectance upon Eu-doping, with the average visible reflectance increasing from 79.5 to 85%, while a slight reduction in the bandgap from 3.24 to 3.22 eV was observed. Fourier-transform infrared (FTIR) and attenuated total reflectance (ATR) spectroscopies displayed similar absorption bands across samples, with Eu co-doping reducing the intensity of the Zn–O vibrational band, indicating fewer Zn–O bonds. Scanning electron microscopy (SEM) showed that AZO crystallites, mainly spherical or quasi-spherical, formed toroidal grains with filled centers. Eu-doping promoted greater grain segregation and size, leading to toroidal morphologies with hollow centers. Photoluminescence (PL) spectroscopy revealed emission bands from 360–700 nm, with strong UV emissions at 378 and 389 nm linked to band-to-band and excitonic transitions. Weaker peaks at 366, 538, and 640 nm in the visible region were attributed to structural defects and impurities, while a 420 nm shoulder linked to interstitial zinc decreased with Eu-doping.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"67 9","pages":"774 - 782"},"PeriodicalIF":1.8,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Synthesising Bi2Te2.7Se0.3 (BTS) composites for the improvement in the thermoelectric performance has gained interest in recent years. In this work, BTS and BTS/reduced graphene oxide (BTS-X wt %, X = 0–9) materials were synthesised by mechanical alloying using a ball mill. Graphite was chemically transformed into graphene oxide (GO) and then subsequently reduced to reduced graphene oxide (rGO). We report that addition of a small quantity of rGO (X ≤ 5 wt %) into Bi2Te2.7Se0.3 improved the thermoelectric performance by improving the charge carrier transport and suppressing the thermal transport at the BTS/rGO interface. Enhanced phonon scattering at the interface reduced the thermal conductivity to ~1.83 W/m K and improved the power factor ~2927 µW m–1 K–2 at 514 K for BTS-5 wt % rGO sample. The peak ZT (ZTmax) of ~0.82 at 514 K was obtained for the BTS-5 wt % rGO composite sample enhancing the peak ZT by ~14% from the pristine. Meanwhile, we observed the ZT average increases from ~0.55 (300–600 K) for BTS to ~0.75 (300–600 K) for BTS-5 wt % rGO sample. This improvement is mainly attributed to the improvement in the Seebeck coefficient and the reduction in the thermal conductivity of the composite material. Furthermore, the addition of rGO into BTS results into the improvement in the hardness of the composite material.","PeriodicalId":731,"journal":{"name":"Physics of the Solid State","volume":"67 9","pages":"802 - 811"},"PeriodicalIF":1.8,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of this hybrid synthesis technique on the photocatalytic activity of pure Bi2Ti2O7 nanopowder is extensively studied. X-ray diffraction analysis established the pyrochlore structure of the synthesized Bi2Ti2O7 nanopowder with well-defined diffraction peaks. The average crystallite size is estimated to be about 16 nm.

UV-Vis spectroscopy reveals a narrow bandgap of 2.72 eV, ideal for efficient photocatalytic activity under visible light. The photoluminescence spectrum demonstrated the lower charge carrier recombination rate, which influences photocatalytic performance. Insights into the photocatalytic activity of Bi2Ti2O7 is acquired through the degradation of a methylene blue dye under visible light (>420 nm). The maximum degradation was achieved within a brief period of 50 min with the apparent reaction rate constant of the catalyst 12.3 × 10–3 min–1.

Unlike conventional GaN heterojunction LEDs, the emission characteristics of the MQW-LEDs are governed by quantum confinement effects (QCE) and polarization field engineering. By optimizing structural parameters, we achieve tunable UV emission across 335–366 nm, with optimized electroluminescence (EL) centered at 342.6–348.7 nm. Deconvolution analysis of EL spectra reveals that the emission blue shift originates from enhanced QCE due to reduced well thickness-an effect that not only increases carrier wavefunction overlap and radiative recombination efficiency by also suppress non-radiative recombination losses by minimizing lattice relaxation and interfacial strain accumulation.
